The Sudoku GP is over for this year. Since the Sudoku World Championship is cancelled, there will be no finals like last year. The final results will be decided based on the preliminary rounds.

There were 31 Estonians participating in the Sudoku GP this year. 17 Estonians managed to complete at least 6 rounds. There were 1029 competitors in total. It is impossible to say the number of different countries, but in general there were participants from many places around the world - mostly from Europe, Asia and North America.
Top three:
1. Tantan Dai - China
2. Tiit Vunk - Estonia
3. Kota Morinishi - Japan

The first 3 also outperformed the next ones by quite a large margin and were relatively close to each other.
